MadSci Network: General Biology |
Well, Enoch---I thought I had heard it all by now but this is the first time that anyone has ever asked me anything like this. I'd be curious to know why this subject interested you. I did a web search and found nothing. I also went through every medical anatomy textbook and dictionary in our local medical center library and found nothing. I then remembered that a science teacher friend of mine had a "real bone" skeleton which he had bought about 30 years ago. It is the size of a 5' 5" male. I paid him a visit and after about 2 hours the two of us came up with an answer for you. 1) We first seperated the hand from the skeleton and weighed it == 33.88 grams 2) the wire that held it together was immovable so we calculated the weight by using comparable wire; that equaled == 9.8 grams 3) we deducted 9.8 from 33.88 and came up with a total of == 24.08 grams for actual weight of the bone 4) We then called a friend who sculpts and a doctor friend -- trying to come up with a consensus on the weight (tissue + blood) to bone ratio. They both told us that it was somewhere between 30-40% 5) so the weight of a 5' 5" male's hand is between 31.28 grams and 33.08 grams The only other thing that you might consider is weight displacement in water, but I don't have a clue on how to make that an accurate measurement without seperating the hand from the body. So, why did you want to know this anyway?
